Age

In 1960 my age was equal to the digits sum of the year of my birth. What is my age now?

Result

n =  77

Solution:

n=2020−1943=77n=2020 - 1943=77

The equations have the following integer solutions:
a = 1+9+c+d
1960 - (1900+c*10+d) = a
a<40
d<10

Number of solutions found: 1
a1=17, c1=4, d1=3

Calculated by our Diofant problems and integer equations.
